摘要： The present invention provides a compact row decoder with multiple voltage support. The row decoder may include a global driver and a plurality of row-level drivers. The global driver may include one or more voltage level shifters that are operable to provide multiple voltages required to drive each of the plurality of row-level drivers. The plurality of row-level drivers each may include only one voltage level shifter. In an example, the row-level driver includes an address decoder implemented in a digital domain providing an address selection signal, a voltage level shifter to convert the address selection signal to an analog domain, and a tow driver receiving driving signals from the global driver. The row driver has no voltage level shifter contained therein. Thus, the row-level drivers and the row decoder may be very compact. The present invention further provides a CMOS image sensor including the row decoder and a method of operating the CMOS image sensor.
